I am trying to use a KeySpan USB to Serial Comm Port interface with software I developed using VB 2008 and both.net 2.0 and.net 3.5 sp1. The software works fine with built in comm ports on a Win 7 64 bit desktop (comm 1) and on an XP Pro desktop. However, when using the same computers and the KeySpan interface both machines crash after a few seconds of receiving continuing stream of messages. The messages are both command and respond interaction and command and then a stream of messages (rate is way below the baud rate of 38.4 kbps).
I have tried the latest drivers listed at the Tripp Lite/KeySpan web site. The same device has worked for years on XP computers using a third party com control and VB 6. Does anyone have any ideas or similar experience with this?
